Description

Technical Field

[0001] This application relates to the field of heat treatment apparatus technology, and more particularly to a heat treatment apparatus for circular knitting needles. Background Technology

[0002] A circular knitting machine cylinder is typically a ring-shaped metal component with numerous needle grooves evenly distributed on its circumference. During operation, the cylinder rotates, and the needles move up and down within these grooves, interacting with the yarn to complete the knitting process. The cylinder surface experiences constant friction with the needles and yarn during knitting, requiring high hardness and excellent wear resistance to ensure both the cylinder's lifespan and the quality of the knitted fabric. Heat treatment can create a fine and uniform martensitic structure on the cylinder surface, significantly improving its hardness and wear resistance. However, existing heat treatment equipment is only suitable for cylinders of a certain specification and cannot be adjusted according to cylinder size. Different sizes of circular knitting machine cylinders necessitate the use of various heat treatment devices, limiting production flexibility and increasing operating costs for businesses.

[0043] Reference Figures 1-4 A heat treatment device for circular knitting syringes includes a treatment platform 1 with a liquid reservoir 11 filled with a liquid for cooling the workpiece and for rapid cooling of the syringe after heat treatment. The treatment platform 1 has a receiving cavity 12, within which a rotary lifting assembly 2 is installed. The rotary lifting assembly 2 is used to adjust the position and height of the workpiece and to rotate it circumferentially. The rotary lifting assembly 2 includes a lifting cylinder component 21, which is a pneumatic actuator connected to an external air pump via a pipeline. The lifting cylinder component 21 has a telescopic end connected to a rotary drive component 22. The rotary drive component 22 is a motor-driven indexing plate in the prior art. The output end of the rotary drive component 22 is connected to a placement tray 3 located within the liquid reservoir 11. The lifting cylinder component 21 changes the position of the rotary drive component 22, thereby changing the height of the placement tray 3. The rotary drive component 22 drives the placement tray 3 to rotate.

[0044] An electromagnetic heating component 4 is provided on one side of the treatment platform 1. The electromagnetic heating component 4 is an electromagnetic heater in the prior art. The electromagnetic heating component 4 has a heating coil 41 and is located above the treatment platform 1. The heating coil 41 heats the syringe from the outer periphery.

[0045] The outer periphery of the tray 3 is provided with several spaced support components 31. The support components 31 are used to support the syringe. The support component 31 includes a support frame 311 and a movable frame 312. The support frame 311 is located on the outer periphery of the tray 3 and is fixed to the tray 3. The support frame 311 has a receiving groove 3111. One end of the movable frame 312 is movably disposed in the receiving groove 3111. By moving the movable frame 312 in the receiving groove 3111, the length of the support component 31 can be extended or shortened.

[0046] The movable frame 312 is provided with several spaced mounting holes 3121, and a limiting shaft 32 is movably mounted on one set of mounting holes 3121. A limiting area for placing a syringe is formed between the several limiting shafts 32.

[0047] The processing table 1 is also equipped with a side grinding assembly 5, which includes a push rod component 51. The push rod component 51 can be any one of the pneumatic push rod, electric push rod or hydraulic push rod in the prior art. The processing table 1 is provided with a support plate 13, and the push rod component 51 is installed on the support plate 13. The telescopic end of the push rod component 51 passes through the support plate 13 and is installed with a placement seat 52. The placement seat 52 is provided with a drive motor 53, and the output end of the drive motor 53 is equipped with a grinding roller 54. The drive motor 53 is a servo drive motor in the prior art. The drive motor 53 provides power for the rotation of the grinding roller 54. When the outer circumference of the grinding roller 54 contacts the outer circumference of the syringe, the outer circumference of the syringe can be ground, eliminating the workpiece transfer process, avoiding secondary positioning errors and improving processing accuracy.

[0048] Based on the above structure, the overall length of the support component 31 is adjusted according to the size of the syringe to be processed, so that the movable frame 312 moves along the length direction of the receiving groove 3111. The limiting shaft 32 is installed in the mounting holes 3121 at different positions according to the diameter range of the syringe within the support component 31. When the syringe is located within the support component 31, the outer periphery of the limiting shaft 32 abuts against the outer periphery of the syringe. The support component 31 is provided with several supports that can fix the syringe from all sides, preventing it from shaking. When heat treatment is required, the lifting cylinder component 21 drives the rotary drive component 22 to move vertically. During this movement, the height of the placement tray 3 is changed, so that the syringe is placed within the heating coil 41. Heat treatment is then performed from the outer periphery of the syringe by the electromagnetic heating component 4. The placement tray 3 is mounted on the rotary drive component 22. During processing, the placement tray 3 rotates, causing the syringe to rotate synchronously, thus ensuring uniform heating of the syringe. After processing, with the cooperation of the lifting cylinder component 21, the placement tray 3 moves the syringe into the liquid storage tank 11, completing the heat treatment operation. After the heat treatment operation, the push rod component 51 moves the placement seat 52, positioning the grinding roller 54 on the outer periphery of the syringe. With the cooperation of the drive motor 53, the outer periphery of the syringe is ground. The rotation of the placement tray 3 causes the syringe to rotate circumferentially, allowing the grinding roller 54 to evenly grind the outer periphery of the syringe, thereby further improving the accuracy of the syringe. Compared to traditional syringes that can only be installed in a single size, the bracket component 31 allows for flexible adjustment of the syringe size, improving installation flexibility. The edge grinding component 5 further grinds the syringe, improving the product's accuracy.

[0049] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5 The center of the tray 3 is provided with a protrusion 33, and the outer periphery of the protrusion 33 is provided with an elastic support component 34. The elastic support component 34 includes an elastic element 341. One end of the elastic element 341 is connected to the outer periphery of the protrusion 33, and the other end is connected to a clamping part 342. The buffering effect of the elastic element 341 allows the clamping part 342 to be slightly adjusted according to the inner diameter of the syringe, which is compatible with different specifications of syringes, eliminating the need for frequent replacement of fixtures and improving the versatility of the device.

[0050] The clamping part 342 moves closer to or further away from the protrusion 33 through the cooperation of the elastic member 341;

[0051] The elastic support component 34 is provided with several parts and is distributed at intervals along the circumference of the protrusion 33. The multiple circumferentially distributed clamping parts 342 make elastic contact with the inner wall of the syringe, avoiding deformation caused by single-point force. Especially during high-temperature heat treatment, the elastic support can alleviate the stress generated by thermal expansion and contraction and protect the accuracy of the syringe. When the syringe is located on the support component 31, the outer circumference of the syringe abuts against the limiting shaft 32, and the inner wall of the syringe abuts against the clamping parts 342. Through the cooperation of the elastic support component 34 and the limiting shaft 32, support can be provided at both ends of the syringe, thereby improving the stability of the syringe during movement and heat treatment.

[0052] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 6 The electromagnetic heating component 4 is provided with a support frame 42 that extends above the processing platform 1. Support seats 421 are provided around the support frame 42. The support seats 421 have protruding seats 4211 that are perpendicularly distributed between them. Support rods 422 are provided on the protruding seats 4211. A receiving plate 423 is installed at the bottom of the support rods 422. Part of the heating coil 41 is located on the receiving plate 423. The support frame 42 stably supports the heating coil 41 above or around the syringe. The rigid connection between the support seat 421 and the protruding seats 4211 can reduce coil vibration in the receiving plate 423. Especially in high-frequency heating, a stable coil position is the key to uniform heating and can avoid local overheating or underheating.

[0053] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 5 The support frame 311 is provided with a limiting hole 3112, and the movable frame 312 is provided with several through holes 3122 that are spaced apart along the length of the movable frame 312. The through holes 3122 and the mounting holes 3121 are vertically distributed on the movable frame 312, and the through holes 3122 and the mounting holes 3121 are connected within the movable frame 312.

[0054] The limiting hole 3112 and the through hole 3122 have the same diameter. When one set of through holes 3122 is aligned with the limiting hole 3112, a pin is connected between the through hole 3122 and the limiting hole 3112 to fix the movable frame 312 on the support frame 311. The through hole 3122 of the movable frame 312 along the length direction can be aligned with the limiting hole 3112 in the support frame 311. The pin is used to fix different positions to adapt to syringes of different heights or lengths, meet the needs of diversified products, and the pin fixation ensures that the movable frame 312 does not shift during the heat treatment process, avoids positioning deviation caused by vibration, ensures process consistency, and improves the flexibility when changing the length.

[0055] In one embodiment, reference is made to Figure 1 and Figure 2 A guide pipe 6 is provided on the liquid storage tank 11. One end of the guide pipe 6 is connected to the inside of the liquid storage tank 11, and the other end extends to the outside of the treatment platform 1. The guide pipe 6 is used to discharge the liquid in the liquid storage tank 11. A solenoid valve 61 is installed on the part of the guide pipe 6 located outside the treatment platform 1. When the solenoid valve 61 is closed, it cuts off the liquid passage to prevent the medium in the liquid storage tank 11 from evaporating or leaking. At the same time, it supplies liquid on demand, reduces waste, and lowers the cost of environmental treatment.

[0056] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 6 The receiving frame 42 is provided with a slide groove 424, and the support base 421 is provided with a slider 4212 corresponding to the slide groove 424. When the slider 4212 moves along the length direction of the slide groove 424, the support base 421 drives the support rod 422 to move synchronously. Since the heating coil 41 that needs to be installed may change for different syringes, the receiving plate 423 can support the heating coil 41 by sliding the slider 4212 according to the size and position of the heating coil 41.

[0057] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 5 The clamping part 342 is provided with an arc-shaped end 3421 on the side facing the syringe. The design of the arc-shaped end 3421 increases the contact area between the clamping part 342 and the syringe, improves the tightness when fitting, and can reduce local pressure, avoid scratches or indentations on the inner wall caused by rigid clamping, thereby improving clamping stability, preventing displacement caused by vibration or rotation during heat treatment, and ensuring heating uniformity.

[0058] In one embodiment, reference is made to Figure 1 and Figure 2 The bottom of the tray 3 is provided with an extension 35 and connected to the rotary drive component 22. The extension 35 further increases the height movement range of the tray 3. When the rotary drive component 22 drives the extension 35 to rotate, the tray 3 rotates synchronously. A sealing gasket is provided at the connection between the extension 35 and the liquid storage tank 11 to prevent the liquid in the liquid storage tank 11 from leaking through the joint between the extension 35 and the liquid storage tank 11. Part of the extension 35 is located in the accommodating cavity 12. With the cooperation of the lifting cylinder component 21, the part of the extension 35 located in the accommodating cavity 12 can be increased or decreased. By extending the height of the tray 3 through the extension 35, it can further adapt to the height difference required by different work positions or workpieces.
